Jennifer’s Passat suddenly started running rough and stalled.\u00a0 She called for help and we trailered it to the shop.<\/p>\n
We pulled the codes and got Random Misfire and and Cylinder 3 and 5 Misfire.\u00a0\u00a0 We tried testing the spark using an inductive spark tester, but none of the wires would reliably light the light.<\/p>\n
We did all the resistance checks that the Bentley manual suggested and every thing checked out.\u00a0 However, it was obvious that the spark was still weak to non existent.<\/p>\n
Despite the lack of firm evidence, we elected to replace the coil pack.\u00a0 The V6 Passat coil pack is only available as a unit that included all three coil packs and the transistor to fire them.<\/p>\n
The coil pack is easy to change. There are four bolts holding the coil pack to the front of the engine.\u00a0 There is one wire connection where the bundle comes in.\u00a0 Then there are the six plug wires.<\/p>\n
Replacing the coil pack quickly cured the misfire condition.<\/p>\n
